J02 SPEKE AND GRANT'S DISCOVERIES. [chap. ii. 
my expedition as terminated by having met them, and 
by their having accomplished the discovery of the Nile 
source; but upon my congratulating them with all my 
heart, upon the honour they had so nobly earned, 
Speke and Grant with characteristic candour and gene¬ 
rosity gave me a map of their route, showing that they 
had been unable to complete the actual exploration of 
the Nile, and that a most important portion still re¬ 
mained to be determined. It appeared that in N. lat. 
2° 17', they had crossed the Nile, which they had tracked 
from the Victoria Lake; but the river, which from its 
exit from that lake had a northern course, turned sud¬ 
denly to the west from Karuma Falls (the point at 
which they crossed it at lat. 2° 17'). They did not see 
the Nile again until they arrived in N. lat. 3° 32', which 
was then flowing from the W.S.W. The natives and 
the King of Unyoro (Kamrasi) had assured them that 
the Nile from the Victoria N’yanza, which they had 
crossed at Karuma, flowed westward for several days’ 
journey, and at length fell into a large lake called the 
Luta N’zige; that this lake came from the south, and 
that the Nile on entering the northern extremity almost 
immediately made its exit, and as a navigable river con¬ 
tinued its course to the north, through the Koshi and 
.Madi countries. Both Speke and Grant attached great 
importance to this lake Luta N’zige, and the former
